Pseudo-ginseng rootlet fermentation liquor capable of increasing content of ginsenoside Rh1, preparation method and application of pseudo-ginseng rootlet fermentation liquor

The invention provides panax notoginseng stigma fermentation liquor for increasing the content of ginsenoside Rh1 as well as a preparation method and application of the panax notoginseng stigma fermentation liquor, and relates to the technical field of probiotic fermentation. The preparation method of the panax notoginseng stigma fermentation liquor comprises the following steps: mixing panax notoginseng stigma with a solvent according to a solid-liquid ratio of 1: (4-8) g/mL, extracting for 20-40 minutes, repeatedly extracting for 1-3 times, collecting filtrate, and concentrating to obtain crude extract; enriching ginsenoside in the crude extract through column chromatography to obtain an enriched solution; and inoculating strain fermentation liquor into the enrichment liquid according to the inoculum size of 8-12%, and fermenting. The invention also provides the panax notoginseng stigma fermentation liquor prepared by the preparation method and application of the panax notoginseng stigma fermentation liquor
